Dual-cylinder valve

To my master, how does a two-cylinder valve work?
Reply #22010-10-11
Bro, is it a double-cylinder angular stroke valve or a double-cylinder linear stroke valve?

Reply to 2# king70868: Is there a difference between linear motion and rotary motion? ? Tell me everything

The advantage of a dual-cylinder design is that self-holding can be achieved easily. The remaining principles are the same as those for single-acting types.

It’s all listed there; you’ll understand if you take a closer look. http://www.tacwell.com If you’re still not clear after checking it, we can discuss each detail separately: QQ:120519927

To put it simply: First, linear double-cylinder types are commonly used in control valves; they offer greater torque compared to single-cylinder types and operate more smoothly, but at a higher cost. II. Angular stroke dual-cylinder systems are commonly used in shut-off valves (especially ball valves the most). Principle: High-pressure gas drives the piston, which in turn moves the toothed push rod and the toothed shaft; this causes axial rotation, which leads to the rotation of the ball and thus its opening or closing. Advantages: High torque, with a linear torque value. Disadvantage: Cannot be reset in emergency situations (the single cylinder has a reset spring).

For two-cylinder valves, a dual-positioner is used for adjustment, with regulation achieved by pressurizing and depressurizing the upper and lower chambers. Such valves generally come equipped with a handwheel mechanism that allows for manual adjustment.

1. Linear double-cylinder types are commonly used in control valves; they offer greater torque compared to single-cylinder types and operate more smoothly, but at a higher cost. It is also used in gate valves. II. Angular-motion double cylinders are commonly used in shut-off valves (especially ball valves the most), and can also be used in angular-motion control valves. Principle: High-pressure gas drives -- piston -- toothed push rod -- toothed shaft -- axial rotation -- sphere rotation -- opening and closing. Advantages: High torque, with a linear torque value. Disadvantage: Cannot be reset in emergency situations (the single cylinder has a reset spring).
